1. Indian Space Research Organisation (ISRO) has announced that Chandrayaan2’s Orbiter payload CLASS has detected charged particles on the moon in its first few days of observation.
2. CLASS has observed intensity variations in its first passage through Moon’s orbit.
3. ISRO said in a statement released on its official website that CLASS is able to detect direct signatures of elements present in the lunar soil.
4. It was also found by the CLASS that best observation occurred when the Sun provides a rich source of x-rays to illuminate the lunar surface.
5. The payload can also detect secondary x-ray emissions resulted from the lunar surface to find out elements like Na, Ca, Al, Si, Ti and Fe.
